How should the spindle bearings of precision CNC lathes be cleaned?
As a key component of the machining center, the spindle bearing of the CNC lathe will directly affect the accuracy, speed, stiffness, temperature rise and noise parameters of the machining center, thereby affecting the machining quality of the workpiece. 1. Keep hands clean and dry: When the CNC lathe spindle bearing is taken out of the package, the operator's hands should be kept clean and dry, because the sweat on the hands can cause corrosion, wear gloves if necessary. 2. Guarantee good lubrication effect: The precision lathe bearing that is taken out should be oiled immediately, and it should be installed without pollution immediately after taking out, and no oil should be added. 3. Packaging should be sealed: Precision lathe bearings should only be cleaned from their original packaging prior to assembly. 4. Correct cleaning: The greased precision bearing cannot be cleaned before assembly, and the non-greased precision lathe bearing must be cleaned before assembly. Dry immediately after cleaning and add anti-rust oil or fat to avoid corrosion. After removing several sets from multiple precision bearing packages sealed with volatile corrosion inhibitors, they should be sealed immediately because the shielding gas of the VIC paper can only be maintained in the sealed package. In order to maintain good machining capability, high-performance bearings are required. The assembly quality of the spindle bearing of the CNC lathe directly affects its working state and service life. Many failures of CNC machining centers are caused by improper bearing assembly, so full attention should be paid to bearing assembly technology.
